Proposal: passing user idle time to systemd-logind

Hi Germano,
That seems an interesting feature and would be great to have in Xfce.
I don't know xfce4-session and xfce4-power-manager sources very well, but I
think the latter already watches when the user is idle, so it seems
to get this logic into xfce4-session and toggle SetIdleHint accordingly.
Please file a bug at requesting this feature.
